ACKn

Acknowledge — The printer pulses this line low after it accepts a byte of data and is ready for

 

more data.

BUSY

Busy — The printer sets this line high when it cannot receive data due to data entry, a full

 

buffer, or error status.

FAULTn

Fault — The printer sets this line low if it reaches an error state.

IPn

Input Prime — This line pulses low to reset the printer and clear the print buffer.

PA0 - PA7

Printer Data Bus —This is the 8-bit parallel data bus. These lines transmit a byte of data to the

 

printer.

PE

Paper Error — The printer sets this line high when it is out of paper.

SELECT

Selected — The printer sets this line high to indicate that it has been selected.

STROBEn

Strobe — This line pulses low when a byte of data is ready. A low pulse on this line clocks the

 

data into the printer.
